立体街区及其实践与研究进展

Three-Dimensional Block and Its Practice and Research Progress

构建立体城市是响应紧凑化城市建设的重要举措之一。立体街区内涵体现在空间形态、功能结构的立体化等方面,其中,多层开放空间系统是立体街区的关键特征。立体街区实践主要包括商业主导型、地形高差型和交通主导型三种类型。近十年的研究集中在立体街区的空间形态、空间使用、优化设计三个方面,呈现出多线并行的特点,研究尺度相对单一,尤其是缺少针对立体街区三维空间使用规律的研究。需要构建全尺度的立体街区形态分析体系和使用绩效评价体系,以及探索两者的关联规律,为立体街区的精细化规划实践提供系统性研究参考。

Building a three-dimensional city is one of the important measures to respond to the compact city construction.The connotation of the three-dimensional block is reflected in the spatial form,the functional structure,etc.Among them,the multiple open space system is the key feature of the three-dimensional block.The three-dimensional block practice mainly includes three types:business-oriented,terrainheight difference,and traffic-oriented.The research in the past ten years has focused on three aspects of spatial form,space use and optimal design of three-dimensional blocks,showing the characteristics of multi-line parallel,and the research scale is relatively single,especially the lack of research on the law of three-dimensional space use of three-dimensional blocks.It is necessary to build a full-scale threedimensional block morphology analysis system and use performance evaluation system,and to explore the relationship between the two,so as to provide a systematic research reference for the refined planning practice of three-dimensional blocks.
